Approximately 2,100 of these "conversions" were reportedly manufactured circa 1877-1878 using a mixture of remaining Model 1860 Army parts and newly manufactured components. These revolvers were manufactured alongside the Single Action Army and are believed to have seen significant use in the Old West. The serial number is within the separate conversion range and is marked, full and partial, on the barrel lug, frame, trigger guard, back strap, and cylinder. The barrel has a German silver blade front sight, ejector mounted on the right, and "COLT'S PT. F. A. MFG. Co. HARTFORD, CT. U.S.A." on top. The cylinder has the standard naval battle scene. The frame has 1871 and 1872 patent markings on the left, "44 CAL" marked on the left of the trigger guard and assembly number "526" marked on the loading gate and arbor pin. Modern replacement wedge.

Fine, retains 70% period retailer applied original nickel finish with a few areas of light flaking and frosting, a few small patches of light pitting, and mostly clear markings and cylinder scene. Grip is very good as lightly sanded and re-oiled with scattered dents concentrated on the right panel and some light handling marks. Mechanically excellent.
